parameters

问题 I'm trying to execute next: $.ajax({ type: 'GET', url: 'http://127.0.0.1:6789/dir', data: "", success: function(data) { /*do something*/ }, dataType: 'html' }); But when it executes, my server receives something like below: http://127.0.0.1:6789/dir?_32567871112 I don't want to pass any parameters. What do I wrong? 回答1: In short, set cache to true in your $.ajax call's options. jQuery adds that for cache breaking. There is an option in jQuery to turn that off: (from http://api.jquery.com

问题 I have 10 actions in one Controller. Every action required ID from request. I want to check ID in constructor for every action, so I want avoid to write the same code 10 times in every action. obviously, In constructor I can not use functions like: $this->params()->fromQuery('paramname'); or $this->params()->fromRoute('paramname'); So, the question is how to get request params in controller's constructor? 回答1: Short answer: you cannot.

问题 I wrote a function to create HTML files and I'm now in the process to improve it a bit. When feeding the function through the pipeline it works fine but it's not resulting in the desired action. This is ok: Create-FileHTML -Path "L:\" -FileName "Title" "Text1", "Text2" L:\ Title Text1 Text2 The is not ok: "Text1", "Text2" | Create-FileHTML -Path "L:\" -FileName "Title" L:\ Title Text1 Text1 L:\ Title Text2 Text2 How is it possible to feed 2 values to the function to have the same result as my

问题 I got a function which wants to send 2 INT parameters back to where it has been called, but not sure what would be the best option, a Dictionary ? or a List or an Array EDITED I am using .Net framework 2 回答1: I assume you mean return 2 values to the caller.

问题 I'm developing a JSF2 site where the users may start a java application through java web start. The app parses mp3 metadata and sends back a xml file with the parsed information. I need some way of identifying the user for each file that is sent to the server and I have not been able to figure out how to do this. In other words the goal is to be able to set the userId in the xml file before the user sends it to the server. In order to do that, I need to somehow have that Id available in the

问题 As described in Wicket redirect: how to pass on parameters and keeps URLs "pretty"?, there are a variety of options for passing parameters in Wicket. However, all of the methods listed on that page use the URL to transmit parameter information. Is there a class that's similar to the PageParameters class except that it hides the information it's transmitting? I don't care about bookmarkability, but I do care about URLs like http://www.example.com/example.html?uniqueId=309308&superSecretValue

问题 I'm using System.Xml.XmlElement as a parameter for sending XML data in WCF. Is this generally the interoperable way to send XML data in WCF, so that, for example, a PHP or Java Web Service will understand it if I'll send it from a WCF Client? I've read that I should never send XML directly as string in WCF.

问题 I want to get a cmb-value before the entry is changed, by using ".oldValue". The value is correctly assigned (according to debugger), but running the SQL Access is asking for a manual entry. Doing the entry manually works fine, so the remaining code should be fine. My Code: Dim CategoryNameBeforeChange As String CategoryNameBeforeChange = Forms!frmCategory!txtCategoryName.OldValue SQL = "UPDATE CategoryTbl " & _ "SET CategoryTbl.CategoryName = Forms!frmCategory!txtCategoryName " & _ "WHERE
